SAFETY PRECAUTIONSWARNING: The chassis of this receiver has a floating

ground with the potential of one half the AC line voltage inrespect to earth ground. Service should not be attempted by

anyone not familiar with the precautions necessary when

working on this type of equipment.

The following precautions must be observed:

1. An isolation transformer must be connected in the power

line between the receiver and the AC line before any ser-

vice is performed on the receiver.

2. Comply with all caution and safety-related notes provid-ed on the side of the cabinet, inside the cabinet, on the

chassis, and the picture tube.

3. When replacing a chassis in the cabinet, always be certain

that all the protective devices are installed properly, such

as control knobs, adjustment covers, shields and barriers.

DO NOT OPERATE THIS TELEVISION RECEIVER

WITHOUT THE PROTECTIVE SHIELD IN POSITION AND

PROPERLY SECURED.

4. Before replacing the back cover of the set, thoroughly

inspect the inside of the cabinet to see that no stray parts

or tools have been left inside.

Before returning any television to the customer, the

service technician must perform the following safety

checks to be sure that the unit is completely safe to

operate without danger of electrical shock.

ANTENNA COLD CHECKRemove AC plug from the 120 VAC outlet and place a

jumper across the two blades. Connect one lead of an ohm-

meter to the jumpered AC plug, and touch the other lead to

each exposed antenna terminal (UHF and VHF antenna ter-

minals). The resistance must measure between 1M ohm and

5.2M ohm. Any resistance value below or above this range

indicates an abnormality which requires corrective action.

LEAKAGE CURRENT CHECKPlug the AC line cord directly into a 120 VAC outlet. (Do not

use an isolation transformer for this check.) Use an AC volt-

meter, that has 5000 ohms per volt or more sensitivity.

Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15 F

150 VAC capacitor, between a known good earth ground

X-RADIATION PRECAUTIONThe primary source of X-RADIATION in solid-state receivers is

the picture tube. The picture tube is specially constructed to

limit X-Ray emission. For continued X-RADIATION protection,

the replacement tube must be the same type as the original

(including the suffix letter in the part numbers). Excessive highvoltage may produce potentially hazardous X-RADIATION. To

avoid such hazards, the high voltage must be maintained within

specific limits. Refer to the X-RADIATION WARNING NOTE on

the CHASSIS SCHEMATIC in this service manual for specific

high voltage limits. If the high voltage exceeds specified limits,

check the components specified on the chassis schematic

diagram and take the necessary corrective action. Carefully

follow the instructions for the +B Voltage Check and the High

Voltage Check to maintain the high voltage within the specifiedlimits.

HIGH VOLTAGE HOLD-DOWN TESTTo prevent X-RADIATION from the picture tube due to

excessive high voltage, a HOLD-DOWN circuit is provided in

the high voltage circuit. Every time the receiver is serviced,

CENTER CONVERGENCE ADJUSTMENT1. Connect a crosshatch generator to antenna terminals.

2. Set Contrast to low level to eliminate blooming. Reduce

Brightness level to obtain black background if necessary.

3. Adjust the angle between the four-pole magnet tabs 1

and 2 (Figure 2), and superimpose the red and blue ver-

tical lines in the center area of the picture screen. See

Figure 4.

4. Keeping the tabs at the same angle, rotate them together

to superimpose the blue and red horizontal lines in the

center area of the picture screen. See Figure 4.

5. Adjust the six-pole magnet tabs 3 and 4 so the con-

verged red/blue line is superimposed on the green line.

This is the same procedure used in steps 3 and 4. SeeFigure 5.

OUTER AREA CONVERGENCE ADJUSTMENTThe outer area convergence is performed by positioning of

the yoke as follows:

1. Move the top of the yoke toward or away from the pic-ture tube. This movement will affect the vertical lines at

the top and bottom and the horizontal lines at the sides.

See Figure 6.

2. Check that splits at 12 oclock and 6 oclock positions

are minimized, adjust yoke for best compromise.

Secure with wedge at 12 oclock position. See Figure 1.

3. Move the side of the yoke toward or away from the pic-

ture tube to converge the horizontal lines at the top and

bottom and the vertical lines at the sides. See Figure 7.4. Check that splits at 12 oclock and 6 o,clock are mini-

mized, adjust yoke for best compromise. Secure yoke

position with the side wedges. See Figure 1.

Note:When re-using the rubber wedges, apply a small

amount of silicone rubber adhesive or hot melt to

each of the wedges.
